Not Returning to Home

I haven’t been able to find anything that was quite the same as the problem I am experiencing. So…

I have a K40 with GERBIL controller. It worked fine at first, but now I am having an issue where the laser head does not return to home while Lightburn software is engaged. If I disconnect my laptop from the K40 I can manually return it to home, and if it isn’t Home at startup, it will go there no problem. It’s only when Lightburn is running and interfaced with my K40 that things don’t work properly.

Any assistance with fixing this issue would be greatly appreciated.
